Hi DUDU, in case you missed it, there's the thread over at the daz forums where a bunch of us are playing around with getting dynamic cloth simulation in Carrara:

 http://www.daz3d.com/forums/viewthread/49954/

 Stringtheory is the one who came up with the concept, and it seems to work, really well and really fast, though we're still trying to find the right settings for different types of cloth behavior, all the experiments and settings are in that thread.  Stringtheory did mention he would put together a tutorial on this, but I don't know when he'll have the time to do it.  I would put up a tutorial myself (even though none of it is my idea, and I would give full credit to Stringtheory, Marcus Severus, Diomede and the others since they really pioneered this approach and I'm just trying to refine it  :)  )  but since we haven't zeroed in on exactly the right settings to use for different types of cloth this is still in the experimental stage right now, and more testing needs to be done.
